antidosis · Lit. “a giving in exchange.” A man who was nominated to perform a liturgy could avoid this duty if he could name another citizen who was richer and better qualified to perform the task. If the man challenged agreed that he was richer, he had to take over the liturgy; if he claimed to be poorer, then the challenger could insist on an exchange of all their property to test the claim—in which case the challenger would himself perform the liturgy as the new owner of the (putatively) greater estate. This process of exchange was called antidosis. The advantage of the system from the viewpoint of the democracy was that it encouraged the rich to be suspicious of each other, instead of being hostile towards the state; but although we know of several challenges, there is no attested case in which the exchange was completed.
